Based on PubMed | Does eating eggs increase the risk of testicular cancer?

Most current evidence does not show that eating eggs increases the risk of testicular cancer. Testicular cancer risk is primarily linked to non-diet factors such as a history of an undescended testicle (cryptorchidism), prior testicular cancer, certain congenital testicular development issues, and possibly family history or HIV infection. ^{[1] [2] [3] [4]}

What established sources say about testicular cancer risk

• Testicular cancer is relatively rare and occurs most often between ages 15–39, with strongest, well-established risk factors being an undescended testicle and a past history of testicular cancer. ^{[1] [3] [4]}
• Large clinical centers and public health resources emphasize that testicular cancer is not linked to specific habits, activities, or lifestyles in a consistent way. ^{[4] [1]}

What we know about eggs and cancer in general

• Some observational studies have reported associations between higher egg intake and certain cancers (for example, gastrointestinal sites), but results are mixed and show only small increases that may be due to confounding factors such as overall dietary patterns, cooking methods, or accompanying foods like processed meats. ^[5]
• Case–control work from select countries has suggested links between high egg intake and several cancers, but these designs are more prone to bias and cannot prove cause and effect; authors themselves call for prospective confirmation. ^[6]

Evidence specific to testicular cancer and diet

• There is no strong, consistent evidence tying egg consumption specifically to testicular cancer risk in the general population. Major medical references that list testicular cancer risk factors do not include eggs or dietary cholesterol as recognized risks. ^{[1] [2] [3] [4]}
• Broader epidemiologic studies of dietary cholesterol and cancer have shown variable results across many cancer sites and do not provide clear causal links for testicular cancer; associations in nutrition-oncology are often influenced by confounding dietary patterns and recall bias. ^{[7] [8] [9]}

Practical takeaways for your diet

• Based on what’s known today, eating eggs in moderation as part of a balanced diet is not considered a proven risk factor for testicular cancer. ^{[4] [1]}
• For overall cancer prevention, guidance focuses on maintaining a healthy weight, being physically active, emphasizing plant-forward eating patterns, limiting processed meats, and moderating alcohol rather than eliminating individual foods like eggs. ^{[10] [11]}

Bottom line

• There is no convincing evidence that eating eggs increases the risk of testicular cancer, and eggs are not considered an established risk factor by major medical resources. ^{[1] [2] [3] [4]}
• If you have known risk factors like an undescended testicle or prior testicular cancer, regular testicular self-awareness and prompt evaluation of any new testicular lump or change remain most important for early detection. ^{[3] [1]}
